Sample Problem

Study the picture carefully, and then write the length by using ruler in cm

.

[a] The pencil is about cm long.

[b] The label A is about cm long.

[c] The label B is about cm long.

[d] The length of the two labels is cm.

[e] Label is the longest. (Enter “A” or “B”.)

[f] The total length of the two labels and pencil is cm.

Solution

The length of the pencil is 5 cm.

Label A is 3 cm long: 3- 0 = 3 cm

Label B is 6 cm long: 10 - 4 = 6 cm

The length of the two labels is 3 cm + 6 cm = 9 cm

Label "B" is the longest

The total length is 3 cm + 6 cm + 5 cm = 14 cm.
